To participate in this 1999 World Championships in Athletics Jake still had to participate and win the competitions in the 5,000 meters and in the 10,000 meters and in the marathon in the 1999 USA Outdoor Track and Field Championships to qualify for the 1999 World Championships in Athletics.
Of course, Jake didn't need to participate in the marathon because as he had won the 1997 World Championships in Athletics he had a guaranteed spot, but he would still participate in the marathon too because he would have to run in the 5,000 meters and 10,000 meters anyway.
Jake had not yet told his mother that he intended to participate, because he could give up if there was something else he was interested in doing on his vacation, but Jake would probably be running at the 1999 World Championships in Athletics.
